Safety Concerns,
Thanks. I understand/extrapolate from your answer that the PHCs are powered independently; and also that you expect to see a specific message if there is any problem including the loss of power. So then what could cause all 3 to go at once (IF that's what happened).
I suppose there is still a possibility that the recorded list of events is incomplete and some earlier items did not go through for some reason?
Somebody reading these logs regularly, could perhaps tell, what is the max. number of messages per second one could expect?
